Miscellaneous Debris is an EP of five cover songs by Primus, released on March 12, 1992. The entire EP features bassist Les Claypool with his then-new fretless six-string Carl Thompson bass, nicknamed the "Rainbow Bass."

In his review for Allmusic, Stephen Thomas Erlewine describes the EP as "Primus' best release". He notes that the band "plays actual songs instead of sketching out a few ideas as an excuse for jamming", which means that "Miscellaneous Debris isn't as weird and alienating as previous albums", concluding that the band's covers "show flashes of brilliance, largely due to the loose yet focused musicianship."[1]
